Tools of ExchangeRebel — pay-per-call APIs for AI agents (x402 on Solana)
	Description		Read-only	Idempotent	Open world
`a2a_send`Send one 1:1 direct message through the A2A ciphertext relay: {from, to\|to_handle, ciphertext (base64, <= 16384 bytes decoded), idempotency_key, client_ts, signature (Ed25519 over the a2a-msg/v1 payload)} -> delivered receipt. Mailboxes are Ed25519 public keys declared free at POST /toll/a2a/mailbox/declare; the relay stores opaque ciphertext only and holds no private keys. The payer of record must equal the sender mailbox. Undeliverable sends are refused FREE before payment. Free pre-check at POST /toll/a2a/send/preflight. Retention 30 days. 1:1 DM only. $0.005 per call — USDC on Solana via x402 (over MCP: call without payment to get the PaymentRequired challenge, then retry with the payment at _meta["x402/payment"]).

`access_crawl`Accessibility findings for every same-origin page in a site's sitemap (max 50 pages) in one combined stored report, priced from the sitemap before payment (x402): $0.05 per page for the first 25 pages, $0.02 per page beyond (price RULED). Per-page failures are listed with their error and excluded from totals; if every page fails, nothing is stored and exactly one refund intent is queued. Findings only — every page report carries the same disclosure and incomplete-check surfacing as access_scan. Call access_crawl_preflight first for the exact price preview for free.

`access_crawl_preflight`FREE preflight for access_crawl.

Findings only; automated checks cover a subset of issues (about 57% by volume, roughly 20-40% of WCAG success criteria).

`auth_surface_check`$0.05 USDC on Solana - the payment buys one signed MCP auth-surface conformance report: submit the server's endpoint URL, its stated canonical URL, and its published declaration documents (protected-resource metadata, authorization-server metadata documents, server card; optionally your own capture of the unauthenticated challenge, graded only in a labelled self-reported tier). The service grades all 38 published checks (mcp-auth-surface/v1, MCP authorization revision 2026-07-28): the declaration checks from your documents, and the live-observation checks against the endpoint itself under the service's fetch fence (a refused or unreachable target is recorded not-observed, never guessed).

It grades the published declarations only: it is not a security certification and says nothing about behaviour behind authentication. The payment includes: the signed full report - every class-(i) check graded, every class-(ii) check graded or recorded not-observed, the coverage block, the evidence manifest - and nothing on the disclosure list.	$0.05 USDC on Solana - the payment buys one signed MCP auth-surface conformance report: submit the server's endpoint URL, its stated canonical URL, and its published declaration documents (protected-resource metadata, authorization-server metadata documents, server card; optionally your own capture of the unauthenticated challenge, graded only in a labelled self-reported tier).

`sec_alerts_poll_alerts`Poll the alerts view of a registered watch: the filings matching the watch's own rules that this service first saw since the cursor — new filings, /A amendments grouped to their base form, and deletion flags from weekly index reconciliation only. Paid via x402: $0.01 — RULED (10000 USDC units / 68000 SOL lamports) per delivered view — one poll delivers ALL matching events since the cursor, up to 200 per poll; it is NOT charged per event. Always call the free preflight first (same watch_id + cursor): GET /toll/secalerts/alerts/preflight returns the pending-event count only (no event content) — pending_count 0 is the complete free answer, so you never pay for an empty view. A settled poll that still delivers zero writes exactly one refund intent (net charge zero, cursor unmoved). If you lose a response, re-poll the same cursor within 7 days: the delivery record is re-served verbatim and free (redelivered: true). first_seen_at is ExchangeRebel's own detection timestamp — the moment this service first recorded the filing in its append-only store. The SEC publishes no availability timestamp, so no seller's first-seen time can be anything other than their own observation. For a filer's first-ever touch, the store is seeded from the filer's returned history and first_seen_at is the seed time (records carry seeded:true). Deletion flags are issued only for removals confirmed by the weekly full-index reconciliation: a deletion_flag event is produced only from a record whose provenance marks it weekly-index-reconciliation-sourced. Removals noticed when a single filer's submissions record is re-read are never issued as deletion alerts by this service. Until the weekly reconciliation is wired to the live store, deletion flags do not fire in production. Honest crossover: polls cost $0.01 (ruled price) per delivered alerts view.
